Benefits of 2-Shot Molding

2-Shot Molding (or 2K Molding) is a process that injects 2 materials simultaneously in a single cycle, allowing for multi-component parts with complex shapes and structures. While technically demanding, it offers key advantages such as high product quality, consistency, productivity, and exceptional design flexibility.

Higher repeatability and accuracy – Less costs and cycle times
Improved bonding and quality, tighter tolerances
More complex aesthetics and haptics (multi-color, multi-material components)

Extensive 2-Shot Molding capabilities

At Optimold, decades of hands-on experience and deep technical expertise in 2-shot molding set us apart. With on-site mold tooling capabilities and a collaborative, solutions-driven approach, we guide our customers through every stage of development, from Mold Design to finished product. Our highly trained engineers offer tailored advice on bonding methods—chemical, mechanical, or catalyst-assisted—to ensure optimal performance. The result: high-quality, precision-molded components that meet stringent requirements at competitive prices.

Advanced 2-Shot Molding facilities

Our 2-Shot Injection Molding workshop is equipped with 3 advanced 2-shot Krauss Maffei machines, delivering high-efficiency, low-cost production ideal for rapid mass manufacturing. Located within a certified ISO Class 7 and class 8 cleanrooms when required, our facility ensures strict contamination control—making it perfectly suited for medical device components. This dual-material molding process enhances product functionality while reducing assembly time and cost, all within a controlled, compliant environment. At our on-site sister company Micro Systems, there are 6 MicroPower 15 Micro Moulding machines with in-line 2-shot capabilities to meet custom requirements.

In-house ultra-precision 2-Shot mold tooling

Having on-site mold tooling and expert engineers is vital for successful 2K injection molding. At Optimold, we partner with Micro Systems—an ISO 9001 and 13485-certified ultra-precision mold maker—to ensure every mold is crafted with exacting standards. This close collaboration enables precise design, material selection, and rapid mold adjustments, guaranteeing high-quality, durable components that meet strict medical industry requirements.

EXPLORE OUR APPLICATIONS

Synergy to streamline the entire Development and Validation process

At Optimold and Micro Systems, we deliver complete end-to-end manufacturing solutions that go far beyond standard injection molding services. True success—especially at scale—relies on getting the entire process right from the start. Our projects begin with Design for Manufacturability (DfM) guided by DFMEA, followed by pilot runs using 2-cavity molds to validate design, prove functionality, and catch issues early—reducing risk and cost. Only then do we scale to full production tooling, typically 8, 16, or 32 cavities, enabling efficient, high-volume manufacturing with consistent quality and compliance. This integrated approach ensures your project is built for long-term success.
